Referring more in detail to the accompanying drawings, the referencecharacter 20 designates an upright support upon which shelving brackets2| and 21a are .adjustably mounted.

The upright support 20 as shown more clearly in Figures 5 6, 8 and 9, isof tubular or channel formation, rectangular in formation and having arear wall 22, side walls 23, spaced front Walls 24 with an inwardlydirected flange 25 at the free edge of each front wall 24 with the inneredges of the flanges 25 notched as at 26 to provide seats for lateralpins carried by the shelving brackets 2| and. 2|a. The spaced walls ofthe notches 26 are slightly inclined upwardly and rearwardly for themore secure seating of the shelving brackets, as shown in Figure 6.

The shelving bracket 2| is shown in Figs. 3 and 6 comprises a horizontalarm 21 and a vertical limb 28, the bracket being of one-piececonstruction and of blade-like form. Laterally directed pins 29 arecarried by the upper end of the vertical limb 28 and when the verticallimb is disposed in the upright channel member 20, the pins 29 areseated in selected notches 26.

A tilting screw arrangement is associated with the lower end of thevertical limb 28 and the up right channel support and as shown moreclearly in Figures 6 to 8, comprises a plate 30 flatly engaged with oneside of the lower end of the vertical limb 2B and carrying end lugs 3|reversely bent to overlie the opposite face of the lower end of thevertical limb 28 as shown in Figure 6. An offset tubular member orbarrel 32 is carried by the plate 30 and extends transversely of thevertical limb 28 and said barrel has a transverse opening intermediateits ends that registers with a similarly formed opening 33 in thevertical limb 28. A nut 34 extends into the opening in the barrel 32 andalso projects into the opening 33 in the vertical limb while the screw35 freely movable through the barrel 32 is threaded to the nut 34 andforms an interlocking connection between the tilting screw plate 30 andthe vertical limb 28 of the bracket. The screw 35 is provided with arelatively large head 36 and constitutes the tilting screw for theadjustment of the horizontal arm 21 of the shelving brackets 2| and 2|a.With the shelving brackets in position in the upright channel support,the tilting screw head 36 projects outward ly of the support andforwardly of the front wall 24 thereof and said tilting screw head 36'is adapted to be engaged with an abutment strap 31 of .U-shape as shownin Figure 8 that straddles the forward side of the upright channelsupport and is provided with a lower end opening slot 38 to facilitateplacement thereof on the upright channel support rearwardly of thetilting screw head 35. Upon operation of the tilting screw 35, theshelving brackets 2| and 2|a are shifted on their pivot pin mountings 29for the correct positioning of the horizontal arms 21 thereof.

From an inspection of Figures 6 and 7, it will be observed that thetilting screw 35 is positioned laterally of the vertical limb 28 of theshelving bracket and another. form of tilting screw which positions thesame in the plane of the vertical limb 28 of the bracket is shown inFigures 16 to 18. The lower end of the vertical limb 28 of the shelvingbracket is provided with side notches 39'and a lower end notch 40. AU-shaped clip comprising side plates 4| and 42 is placed upon the lowerend of the vertical limb 28, the plate 42 being cut away at its corneredges as at 43 and shown by dotted lines in Fig.

16, thesecut-away portions registering with the side notches 39 in thevertical limb while the plate 4| of the clip carries lateral lugs 44 atits free corners that are adapted to be bent for reception in the sidenotches Hand to overlie the plate 42 as illustrated, this connectionsecuring the clip element of the tilting screw upon the lower end of thevertical limb. The outer end of the clip is in the form of a tubularbarrel 45 that carries the side plates 4| and 42 and said barrel isprovided with a transverse opening inter mediate its ends for thereception of the nut 46 that extends into the end notch 49 in thevertical limb, the tilting screw 47 freely passing through the barrel 45and threading through the nut 46 and provided upon its outer end with arelatively large abutment head 48. The foregoing tilting screwarrangement presents the tilting screw in the plane of the vertical limb28 of the shelving bracket.

A saddle 49 of U-shape in end elevation is received upon the upper sideof the horizontal arm 2'! of the shelving bracket, being bolted orotherwise secured thereto as at 59 and provided with laterally directedflanges 5! at the lower ends of the sides thereof for the support of theadjacent ends of shelf boards, the shelf boards being of a thickness topresent the upper edge of the saddle 49 in the plane thereof. Theflanges 5| of the saddles 49 are provided with key-hole slots 52 toreceive lug pins depending from the shelf board for the anchoring of thelatter to the flanges, but it is to be understood thatother forms offastening means may be provided. The shelf boards are designated by thereference character 53.

To retain the shelving brackets rigidly positioned upon the uprightchannel support, there is provided a spring clip or spacer shown indetail in Figure 14 and comprising a pair of legs 54 carried by a loophead 55, one of the legs being'longer than the other to facilitateplacement thereof upon the bracket. The spring or spacer clip has thelegs 54 thereof straddling the horizontal arm 21 of the bracket betweenthe forward side of the upright channel support 29 and the adjacent endof the saddle 49 and when so disposed, movement of the shelving bracketrelative to the upright channel support is prevented,'the spring clipacting to prevent displacing movement of the pin support 29 relative tothe notches 26. When it is desired to vertically adjust the shelvingbrackets 2| and 2|a with respect to the upright channel support 20, thespring or spacer clip is disengaged from the bracket whereupon pins 29may be moved further rearwardly into the upright channel support to bedisplaced from the notches 26 so that the vertical limb 28 of thebracket may be shifted in the upright channel support and the pins 29positioned in a selected notch 26. The spring or spacer clip is thenreplaced and the shelving bracket is again rigidly mounted upon theupright channel support.

The saddles 49 are desired for the support of shelf board ends and it isalso intended to employ the form of shelving bracket 2! shown in detailin Figure 15 for the support of shelf boards intermediate their ends.The bracket 2|a is provided on the upper edge of its horizontal arm 2111with a laterally directed angle flange 5| a and the shelf boards aresuitably anchored thereto. The bracket 2|a is provided with laterallydirected pins 29a for the support thereof in flange notches 26 and thevertical limb 23a of the bracket is provided with a slotted opening 33a,side notches 39a and an end notch 49a to facilitate attachment theretoof either form of tilting screw arrangement shown in Figures 6 to 9 orFigs. 16 to 18.

The several upright channel members of a unit may be connected by bracebars, as shown in Figs. 10 and 11, the connection between the upper endsclosedby avertical flange Slisprovidedtvith an indenture 58 to receive afinger 59 struck-out from the vertical member 51 to retain the angleclip in position against displacement. A brace bar or rodfiilis securedatits ,endsto the horizontal fiangesfifi of theangle clips. The uprightsupports are further connected by brace bars 60 intermediate their upperand lower ends by means of angle clips, each including a horizontalflange BI and a depending flange 62 the latter being provided with lowerend opening notches 63 tapering toward their upper ends andcommunicating with cross slots 64 'topermit positioning of an anchorscrew in either end of the slot for the rigid mounting of the angle clipThe brace rodor bar 60 is anchored atits ends to the of the horizontalflanges 6|. V

Perpendicular brace boards 65 each has an end thereof positioned in thelower end of the upright channel support and anchored therein bytransverse fastening elements 66 and said boards 65 have secured totheir upper edges a lower rigid shelf board 61 and a front end finishingboard or panel 68. The adjustable shelving brackets and support may beused for original installation, but it is primarily intended that theybe employed for replacement work and in such instances, the uprightchannel support may be anchored in any convenient manner to a wall and afront finishing panel 69 positioned between adjacent upright supportsand substantially in line with their forward edges as illustrated inFigs. 10 and 11 so that the upright supports are hidden from view exceptfor the forward open sides thereof.

From the above detailed description of the invention, it is believedthat the construction and upper sides use thereof will at once beapparent and while there are herein shown and described the preferredembodiments of the invention, it is nevertheless to be understoodthat'minor changes may be made therein without departing from the spiritand scope of the invention as claimed.
